The Light Sword, also known as a Katana, is one of many weapons in TRON: Legacy formed by a baton. The baton becomes the hilt of the weapon, while a program's own energy is channelled into forming a blade of light.

A sword is featured in the battle at the End of Line Club, with Quorra employing one against the Black Guards. She also draws her sword on Clu in a later fight to protect Sam. The sword blade usually matches the color of the program/user's circuitry color.
